I am looking at yet another project, a Ditch Witch with a Wisconsin engine and rock teeth. However it is like no Ditch Witch I have seen. The trencher is belt drive to the gearbox and chain drive to the differentials. Both axle pinions are tied to one driveshaft that goes to the chain to the gearbox. There is no steering wheel but only brakes on fixed axles, making it a skid steer model. It it definately older than when it broke down in 1990, but does anyone have an idea on the year/model of this thing? Rust has taken away the ID plate.
